I snor and drinkt it today, thank you.
Also as you may have noticed, the picture didn't get as good as it can be.
I used the treshold tool to cut out the circle, pasted it onto a bigger canvas and filled the background from a sample from the original picture.
This causes the circle to look kinda broken and the background doesn't look quite as authentic and organic as the original.
I'll have another go at it and post an improved version later.
